Yonik Seeley created SOLR-7957:
----------------------------------
Summary: simplify ResultContext / TransformContext
Key: SOLR-7957
URL: https://issues.apache.org/jira/browse/SOLR-7957
Project: Solr
Issue Type: Bug
Components: rch, search
Reporter: Yonik Seeley
Fix For: Trunk
Today we have a ResultContext which simply has two public variables query and
docList. For writing a response, those fields are used to create a
DocsStreamer which creates a TransformContext for transformers (which just
copies the values like searcher, req, q, etc again).
It seems the all the methods on TransformContext could be simply moved to
ResultContext.
Only exception is "iterator" needed by ScoreAugmenter, but we could simply pass
down the score in the transform() method as well.
This would result in a ResultContext that could do things like support multiple
queries with different return fields, and things like returning a list of docs
from another core (think cross-core join).
